If you double the diameter of a circle what happens to the area?

User Avatar
It becomes 4 times as large. Here is a simple example: A = πr2 For diameter 2, A = π For diameter 4, A = 22 * π = 4π.

How big is 36x24?

User Avatar
36x24 what value? inches, feet, yards, miles,metres,centimetres, millimetres? It's impossible to answer in that context. If you only mean 36x24 as a multiplication problem, then it equals 864. If you want to simplify 36x24 ( like a ratio, I guess), then it becomes 18x12, 9x6, and 3x2. * * * * * I disagree with the last sentence because a ratio is denoted by ":" or "/", not "x".

What is the width of a house in meters?

User Avatar
This cannot be answered without more information. No it can't, and I'm amazed how many enquirers seem not to realise that. However, I suspect this enquirer really wanted to know how to convert the dimension from feet to metres. (That is the right spelling - it's a French invention and word.) If so, 1 metre = 3.280 feet or 1 foot = 0.305 metre.

How do you find the radius if you have the circumference?

User Avatar
Circumference divided by pi to find the diameter then divide that by 2 to give you answer!! Formula: R=c/pi/2 eg. circumference =60 so, 60 divided by pi = 19.098, then divide 19.098 by 2 to give you 9.549!!

Is a triangle supplementary or complementary?

User Avatar
Supplementary: two or more angles equal 180 degrees. Complementary: two or more angles equal 90 degrees. All three angles of a triangle will always add up to 180 degrees, therefore it is supplementary.

What instrument measures angles?

User Avatar
A protractor, compass, speed square, goniometer, theodolites, sextant, or angle finder can be used to measure angles. A protractor is a circular or semi circular instrument for measuring angles and some have existed from ancient times. A half circular protractor is marked for 180 degrees and a full circle for 360 degrees. Protractors usually have two sets of numbers going in opposite directions, so be careful which side you use. When in doubt you should ask yourself is the angle greater or smaller that 90 degrees. An inclinometer measures the slope (aka grade or "incline") on mountain roads and trails. Practice lining up and reading a protractor while you measure a set of angles in this fun learning activity. The angles may range from 0° to 180°. The interactive protractor is already lined up with the vertex of each angle but you will have to rotate the protractor into proper position. The margin of error is only 1° and you must report measurement to the nearest whole number. A protractor measures angles whereas a compass draws angles. The typical protractor is 180 degrees. Protractors can also be circular and measure up to a full 360 degrees. Other methods of measuring angles include using a compass, and length measuring devices (rulers, tape measures, etc.) combined with trigonometry. Estimated angle measures can also use "devices." For example, the corner of a page can tell you if an angle is greater than or less than 90 degrees. Navigators in the old days would use a sextant for measuring angles. In more recent times they used a transit. A quadrant is yet another tool for measuring the angle between the horizon and heavenly bodies, also useful for navigation. A protractor can be used to measure an angle.

What are some non examples of density in real life?

User Avatar
Thought is a non-example of density (unless you happen to be thinking about density!) Any abstract concept should fit the bill.

A five-sided shape is called a pentagon. A pentagon may be regular (all sides and angles are the same) or irregular (the opposite of regular).

What is the difference between a pyramid and a prism?

User Avatar
A prism has 2 bases and a pyramid only 1. In a prism, the two bases are "joined" together by rectangles. In a pyramid, a triangle is attached to each side of the base, with the free corners of each triangle meeting at an apex.

What is a non regular tessellation?

User Avatar
Non-regular tessellations is a tessellation in which there is no restriction on the order of the polygons around vertices. There is an infinite number of such tessellations. These are tessellations with nonregular simple convex or concave polygons. All triangles and quadrilaterals will tessellate. Some pentagons and hexagons will.

Is it possible for equipotential lines to cross?

User Avatar
Equipotentials cannot cross because they relate to places with a given value for potential. Lines of force meet at the charge or point of mass. They can cross if they relate to the same potential. Think of two mountain chains of unvarying height crossing each-other.
